| Abstract: | A compound eye simulated by microlens array was fabricated by photolithography and ion-exchange.The microlens array with 3D gradient index distribution,gapless arrangement and fine optical characteristics is buried in the convex glass substrate.Each hexagonal microlens in the array has a spot size,the center distance between two adjacent microlenses and the buried depth of 4.92 μm,0.5 mm and 0.194 mm,respectively.The measurement results show that the fabricated microlens array has symmetrical optical features,and the focal length of microlens decreases a little from the center to the edge of the substrate while N.A increases a little.The fill factor of the microlens array reaches 100% nearly.This spherical microlens array can simulate a compound eye in some optical characteristics. |
